IMPROVEMENT IN ANTI-FR'IGTION BoxEs FOR'AXLES.

Specification i'urmiu part of Letters Patent N0. 110,160, dated December 13, 1870.

To all 'whom 'it 'may concern Be it known that I, WrLLiAai O. Rnin, ot' Vienna, in the county of Forsyth and State of North Carolina, have invented a new and Improved Anti-Friction Box for Axles, Shaftin g, &c.; and I do hereby declare the following to be a full, clear, and exact description of the saine, reference being had to the accompanyixigdrawing, making a part of this specification, iu whicl c Figure 1 is a longitudinal, and Fig. 2 a trau-sverse vertical, section. Y

This invention relates to improvements in that class of .anti-friction hubs or boxes for wagon-axles, 85e., in which the axle rests on balls or rollers, soarran ged as to travel around it.

The improvement consists in so constructing and arranging the respective parts that the salue balls which sustain the axle-journal shall also prevent friction between the collars and uut of the axle and the cnds of thepipcbox.

'.Lhc imf'cntion also contemplates the greatest simplicit-yot construction and adaptability for adjustment.

In other inventions of this class constructed upon analogous princlples there is a greater number of parts and a more complicated and cuinbrousarrangement of them, there being also no provision for obviating'end friction of the axle-journal, except by a series of balls separate from those "on which said journal rests.

l'n the drawing, A is the axle. a. is the axlebox; b I), the rings, set within the box ateach end,and flush with its internal surface, said rings being each providcdwith two external longitudinal flanges, e, projecting from oppo-` site `sides, which iian'gcs enter corresponding furrows niade for, their reception lengthwise of the internal surface of the box, the rings being by this means stayed against pressure exerted endwise. d d are the channels between the inner ends of the rin gs and the shoulders c c of the box. ff are.theielianiiels'in the box at the outer ends of the rings. h arc the balls which occupy the channels d. al are the balls'which occupy the channels f. k are the nuts 5 l l, the air-spaces'between the nuts and box, andxm the air-space between thc axle and bex.

It will be observed that both the balls It and pose specified. i
